Fractional PLL (fPLL)

A fractional PLL (fPLL) is an alternate transmit PLL used for generating low clock frequencies for low data rate applications. fPLLs support both integer frequency synthesis and fine resolution fractional frequency synthesis. Unlike the ATX PLL, the fPLL can be used to synthesize frequencies that can drive the core through the FPGA fabric clock networks.
